A concussion is a mild traumatic brain injury; bleeding inside the skull and other brain injuries are different conditions. Call 911 or go to an emergency department for the danger signs below. For non-emergency concerns, contact a healthcare provider and let that provider decide what evaluation or imaging is appropriate.Call 911 for Brain-Injury Danger SignsThe Centers for Disease Control and Prevention (CDC) says some symptoms of a mild traumatic brain injury may appear immediately, while others may not be noticed for hours or days. It also identifies danger signs that need immediate emergency care. After a blow or jolt to the head or body, call 911 or go to an emergency department if the person:has a headache that keeps worsening or does not go away;has repeated vomiting;has a seizure, weakness, numbness, or noticeably reduced coordination;has slurred speech, unusual behavior, increasing confusion, agitation, or restlessness;has one pupil larger than the other; orloses consciousness, becomes increasingly drowsy, or cannot be awakened.Follow the 911 dispatcher\u2019s instructions. This list is not a substitute for emergency assessment, and it should not be used to rule out a serious condition. The CDC publishes additional danger signs for infants and children on the same page.Concussion, Intracranial Bleeding, and Other TBI Are Not Interchangeable\u201cHidden brain injury\u201d is a plain-language description, not a medical diagnosis. The CDC defines a traumatic brain injury (TBI) as an injury that affects how the brain works. A collision can produce a bump, blow, or jolt to the head, or a hit to the body that rapidly moves the head and brain. A qualified healthcare provider must decide whether the event and examination support a diagnosis.Concussion or mild TBIA concussion is a type of mild TBI. \u201cMild\u201d describes the clinical classification; it does not mean that every person has the same symptoms or recovery. The CDC notes that a mild TBI may affect thinking, memory, mood, sleep, balance, or other functions. Symptoms alone can overlap with other conditions, so a legal article cannot determine whether a reader has a concussion.Bleeding inside the skullIntracranial bleeding is not another name for concussion. Bleeding may occur within brain tissue or between the brain and skull, and it can create an emergency. The CDC explains that a scan may sometimes be used when a clinician identifies a risk of bleeding. The worsening neurological signs above are reasons to seek emergency help, not reasons to wait for a routine appointment.Other traumatic brain injuriesTBI can range from mild to severe and may involve different structural or functional changes. A visible cut, a normal-looking scalp, loss of consciousness, or the absence of loss of consciousness does not establish the diagnosis or severity by itself. The firm\u2019s Idaho brain-injury practice page describes the legal help available after the person\u2019s immediate health needs are addressed.Symptoms a Healthcare Provider May Need to EvaluateThe CDC groups possible mild-TBI symptoms by how a person feels, thinks, acts, and sleeps. Examples include headache, dizziness or balance problems, nausea, vision problems, sensitivity to light or noise, fatigue, concentration or memory difficulty, feeling slowed or foggy, irritability, anxiety, sadness, and sleep changes. A person may notice a symptom later, and family members may notice a functional change first.Those symptoms are not specific to TBI. Their presence does not prove a concussion, and their absence from a short checklist does not rule one out. Contact an appropriate healthcare provider if you are concerned about a possible mild TBI. If symptoms worsen or a danger sign appears, use emergency care rather than relying on this article.What Imaging Can\u2014and Cannot\u2014AnswerClinical evaluation comes first. The CDC\u2019s adult mild-TBI guidance tells emergency clinicians not to order CT or MRI routinely for every suspected mild TBI and to use clinical decision rules to determine when imaging is needed. That guidance does not mean imaging is never appropriate. A clinician may order a CT or another study when the history, examination, medications, age, or other risk factors make it appropriate.A scan is not required to \u201cspot\u201d every concussion, and a normal scan does not independently decide every functional complaint. Conversely, imaging may help assess bleeding, fractures, or other structural problems when clinically indicated. A plain head X-ray can show bone, but it does not assess brain tissue and should not be presented as a test that diagnoses TBI. The ordering clinician should explain what a test is intended to evaluate.Put Health Decisions Before Claim DocumentationSeek care because of health concerns, not to create a claim record. Follow the individualized discharge and return-to-activity instructions from the treating provider. If a symptom appears, changes, or persists, describe what is happening accurately and ask the provider what to do. Do not change medication, activity, work, driving, or follow-up plans based on a legal website.After immediate health needs are addressed, preserve ordinary records without turning treatment into an evidence exercise:keep discharge instructions, referrals, test reports, and appointment summaries;give providers an accurate history, including earlier head injuries and health conditions;record specific functional changes, such as missed work or difficulty completing a familiar task, without guessing at a diagnosis;save crash photographs, witness information, video, and insurance correspondence; andavoid posting medical conclusions or activity snapshots on social media.How Causation and Loss Are Evaluated in an Idaho ClaimA later diagnosis does not automatically prove that a crash caused it, and a disagreement over diagnosis does not by itself defeat a claim. The evidence must connect the collision to the condition and to the claimed loss. Relevant information may include the crash forces, symptoms and function before and after the collision, contemporaneous records, prior injuries, intervening events, clinician opinions, work records, and testimony from people with first-hand observations.Potentially recoverable losses depend on proof and the governing law. They may include reasonable injury-related medical expense, income loss, reduced earning capacity, and noneconomic harm. The general guide to Idaho personal-injury evidence explains how records, witnesses, and preservation fit together. Deadlines also vary by defendant and facts; review the separate Idaho filing-deadline guide rather than assuming every claim has the same time limit.Frequently Asked QuestionsCan a concussion happen without hitting the windshield?Potentially. The CDC explains that a mild TBI may follow a blow or jolt to the head or a hit to the body that rapidly moves the head and brain. Whether a particular crash caused a concussion requires medical and factual evaluation.Does a normal CT mean there was no concussion?Not necessarily. The CDC says a brain scan is not required to identify every mild TBI or concussion. CT may instead be used when a provider is concerned about bleeding or another structural injury. Ask the treating provider what the result does and does not show.Should I wait for symptoms before contacting a provider?This article cannot make that decision for an individual. Use emergency care for the listed danger signs. For other concerns after a head or body jolt, contact a healthcare provider for advice based on the person\u2019s circumstances.Sources and Medical ReferencesCDC, Symptoms of Mild TBI and Concussion \u2014 symptom categories and emergency danger signs; updated September 15, 2025CDC, About Mild TBI and Concussion \u2014 definitions, clinical assessment, and the role of brain scans; updated September 15, 2025CDC, Mild TBI Management Guideline \u2014 adult emergency-department imaging and discharge resources; updated July 29, 2025MedlinePlus, Head Injury\u2014First Aid \u2014 emergency response information; review date October 14, 2025RadiologyInfo.org, Head Injury \u2014 roles of CT, MRI, and skull X-ray; reviewed June 1, 2026Discuss the Legal Record After Immediate CareOnce urgent health issues are being handled, Attorneys of Idaho can evaluate the crash evidence, insurance, causation disputes, and documented losses.
